Virtual reality-based simulation improves gynecologic brachytherapy proficiency, engagement, and trainee...

Area of Science:

• Medical Education
• Radiation Oncology
• Gynecologic Oncology

Background:

• Intracavitary brachytherapy is crucial for cervical cancer treatment, offering high local control and survival rates.
• Resident confidence in performing brachytherapy is limited, often due to insufficient practice and low caseloads.

Purpose of the Study:

• To evaluate the effectiveness of virtual reality (VR)-based intracavitary brachytherapy simulation in improving resident confidence, engagement, and proficiency.
• To address the barrier of limited caseloads in resident brachytherapy training.

Main Methods:

• A VR training module was developed, featuring a simulated intracavitary brachytherapy case.
• Residents performed a timed pelvic brachytherapy procedure on a simulator before and after VR module exposure.
• Objective measures of implant quality and pre/post-simulation questionnaires assessed confidence and skill.

Main Results:

• Post-simulation, resident confidence improved significantly (1.43 to 3.36).
• Subjective technical skills in assembly and insertion, and objective implant quality scores also increased.
• Procedure time decreased (5:51 to 3:34), and median technical proficiency rose from 4/5 to 5/5.

Conclusions:

• VR intracavitary brachytherapy simulation enhances resident self-confidence, technical skills, and willingness to perform the procedure.
• VR offers an immersive, engaging, and cost-effective training solution, potentially increasing resident interest in brachytherapy.
